Retractable floor barriers are provided that can be quickly opened and closed by pneumatic actuators and operated by the closing and opening of an electrical circuit. The retractable floor barriers can be used at the docks of trains and subway stations to prevent accidental falls therefrom.

A barrier includes a frame and a gate engaged within the frame, the barrier has a first state and a second state, a length of the frame in the second state being smaller than that in the first state, and a length of the gate in the second state being smaller than that in the first state.

The present lift lock is employed on a gate that is swingable and liftable on a first axis. In a first position the lift lock is on the first axis and in a blocking position that prevents the gate from being lifted relative to a barrier having the gate. The lift lock is slideable away from the first position on the axis to a second position away from the axis where the lift lock is in an unblocking position, thereby permitting the gate to be lifted on the axis. The lift lock snaps into and out of the second position.

Described is a pallet including a base having a length extending between a first end and a second end opposite the first end and a width transverse to the length; and a cage removably coupled to the base.

A gate apparatus that includes a gate, an elongate member or gate base for the ends of the gate, and a stairway post adapter such that a wooden stairway post can serve as a base for a gate without harming the wood of the stairway post. The stairway post adapter includes a vertical or longitudinally running channel for receiving the gate base, a horizontally or laterally extending channel for receiving a strap, and a recess or receptor or face for confronting a section of a stairway post. The gate base includes an upper and lower eyelet. Each of the ends of the gate includes upper and lower pins for engaging the upper and lower eyelets of the gate bases. On the hinge side of the gate, the pins are relatively long and remain in the eyelets as the gate is lifted and swung. On the latch side of the gate, the pins are relatively short such that that latch side of the gate can be lifted and disengaged from the eyelets and then swung open. The gate is extendable and retractable in length, and is reversible.

A gate assembly including a pivoting gate element secured to a doorway and/or passageway and employing a dual actuator latching mechanism having a simple yet unique locking lever and pawl mechanism for remote and manual latch release freeing the gate to swing to an open position, and automatic re-locking of the latching mechanism. The gate assembly includes a frame element for supporting the pivoting gate element and securing the gate to a doorway and/or passageway as well as latching the gate to a closed position at the frame element.

The invention relates to a sliding security gate inside a pocket attached to an interior pre-hung hinged door. These pocket sliding security gates can be assembled inside any doorway opening of one's home for the protection of babies, toddlers, pets, and disabled elderly. On one hand, the Pre-Hung Hinged Door and Pocket Sliding Security Gate can be used as a dual functioned component that can be used in a normal setting to provide privacy; on the other hand, the Pre-Hung Hinged Door and Pocket Sliding Security Gate can be used as a half door that is assembled as a pocket sliding security gate to provide safety and security to the vulnerable population listed above. In addition, this pocket sliding security gate also has an alarm attached to the security gate so that when it opens, the alarm sounds to let the gatekeeper know that the security has been breached.

Provided is an adjustable barrier having a central hinge having a cylindrical post and an axis of rotation; a first expandable section coupled to the cylindrical post of the central hinge by at least a first connector; and a second expandable section coupled to the cylindrical post of the central hinge by at least a second connector. At least one of the first and second expandable sections is configured to articulate around the axis of rotation of the central hinge forming an articulation angle between the first and second expandable sections.

A safety gate is configured to be mounted at a gateway and has a frame and a gate body. The frame is configured to be mounted between two walls disposed at two sides of the gateway. The frame has two sides and two first positioning assemblies respectively disposed at the two sides of the frame. The gate body is disposed in the frame and has two sides and two first pivot assemblies respectively disposed at the two sides of the gate body. The first pivot assembly at each side of the gate body is configured to detachably and pivotally connect with the first positioning assembly at a respective one of the sides of the frame.

A retraction barrier can abut objects in the environment for safeguarding. The retraction barrier has multiple longitudinal poles separate from each other and multiple lateral poles separate from each other. The longitudinal poles are connected with the longitudinal poles so that the retraction barrier forms a grid, making the retraction barrier capable of isolating something. The longitudinal poles and lateral poles are each a retractable pole. Lengths of the longitudinal poles and the lateral poles can be changed so that each end of the longitudinal poles and the lateral poles can abut an object in the environment, so the retraction barrier can be secured with objects of any dimensions and shapes. For storage of the retraction barrier, the lateral poles and the longitudinal poles are retracted, so that the volume of the retraction barrier is lessened for ease in carriage.
